Unacceptable service

Once again I went to Game stores in 89 President Street, tried to make a purchase on my own account for R298.68 and again told my card doesn't swipe its not the first time I'm lodging this as the same store refused to take my payment because the card "doesn't swipe" funny thing that bothers me is that I made a payment at Jabulani mall for R1000 and even purchased a cellphone using the same card and all was well never even once did I hear anything wrong regarding the card.. Your jhb staff is completely unprofessional and don't know what customer service is and Amukelani Mathye is just as horrible if not worse they don't respect customers especially females because the male customer treated before me was treated with respect and all smiles they made conversations and when I had to be served not even a greeting nor service this is really uncalled for and needs to be addressed
